I believe QMT does contain a velocity element. The problem is not that QMT doesn't account for velocity. It does. The problem is...moda0306 wrote: His equation isn't really quantity theory though, because it contains a velocity element.
And Monetarists — who love to cite velocity — have been way off the mark. Here's an article from 1986:Critics of the theory argue that money velocity is not stable and, in the short-run, prices are sticky, so the direct relationship between money supply and price level does not hold.

Fortune: MONETARISM ISN'T DEAD Critics say the theory doesn't work because the world has changed. Here's why they are wrong
The article ends with the following paragraph:
Next year?? That was 1986! Monetarists will suddenly claim they are correct the day inflation returns. Annny daaay now...The Fed's flexible policy drove the U.S. economy into the Great Depression in the Thirties and into prolonged inflation in the mid-Sixties. YET MANY POLITICIANS and economic columnists have been calling for more Fed activism than ever before. All those appeals come down to asking the Fed to pursue a more inflationary policy in hopes of temporarily spurring economic growth. The arguments for pumping out more money can be wildly inventive. Take the oil situation. Many people have been arguing that the Fed can safely apply more stimulus now because the drop in oil prices reduces inflation. But many of those same people also wanted more stimulus when oil prices were rising in the Seventies. Back then they argued that faster money growth was needed to counteract the depressing effect that oil price increases were having on the economy. They apparently have one rule of thumb: whatever happens, raise money growth. The monetarist prescription of stable and predictable noninflationary policy is much more likely to foster sustained economic growth. But it has considerably less political appeal than an activist policy. Indeed, since it deprives political entrepreneurs of the chance to manipulate money growth for near-term benefits, it has no political appeal at all. That probably is the greatest reason for the political death of monetarism. It will remain dead at least until the consequences of its demise gradually emerge and inflation accelerates again. Unless the Fed changes its ways or we are blessed with another bout of extraordinary good luck, that should happen sometime next year.
News flash to Monetarists.... There is no simple nifty formula that predicts inflation based on government spending.
